o My invention relates to headlights, andfmore particularly to non-glare headlights.' l It is a purpose of `my invention to provide-a new and improved headlight comprising new and improved means for mounting the lamp in'the headlight so that there willbe no direct light from the lamp shining out through the lens, but all the light will be reflected by the reflector provided for that purpose in the headlighti `V` It is a further purpose ofmy inventionto provide. a mounting for a headlight comprising means whereby the lamp is so mounted that the same faces the reflector, or in other words, so that thelamp socket which receives the lamp will havethe lamp receiving opening thereof fac` ing the upper portion of the reectorsnear the innermost portion thereof, or adjacent the axis of the reflector wheresaid axis meets said reflec` tor surface. The axis of thesocket preferably extends at an obliquelangle to the .axis of the reflector` so as to be inclined in a directionsuch that the lamp receiving opening will face a `portion of the reflector slightly above the axialV centerthereof,4 and so that the axis of the reflector and `the axis of the socket willmake an.angle of approximately 15 degrees to each other. It Vis another purpose of my inventiontolpro- ,vide- `a mounting for a lamp bulb in a headlight which` will hold thebulb in a reverse position from that usually occupied by thebulb, or:with the metal end or base thereof nearest the lens, so as to utilize the structure of bulbs which allow only a sm'all'portion'of the rays of 'vlightwtofex-A tendffrom the filament toward the base of the bulb.v fIt is a further purpose ofmy invention to pro-v vide a mounting for a lamp loullov in a headlight comprising a tubular standard having `a lamp receiving opening'in the upper end thereof, which is directed in a general direction toward the re, flector of the headlight, and which is provided with a shield for keeping any direct raysof light Vfrom the filament of the bulb from shiningout through the lens of the headlight. l AItis, a" further purpose of my invention to provide 'a device vof the above mentioned character having asheld that is formed by providing a widened orenlarged portion at theV upper e'ndwof the standard, which isA so shaped; and' so ylocated 'festive as,r ,a shield-g winch is integral; with said tubular' standard andl which 'extends'V upwardly therefrom at an oblique angle to preventany up# ward passage of the rays of light from the filament abovezthe upper end of the standard;

It is" another purpose of my invention to jpro`A vide meansfor adjusting the focus of a headlight ofrtl'lel above mentioned character by providing meansforadjusting the standard in a directie parallel to the axis of the reflector. l

Itis'another purpose of my invention to pro- 5l videa shield '-of the above mentioned character, which isprovided with a reflecting surface, this being preferably obtained by chromium plating theshield. Y

Other objects-and advantages of my invention 10 wil'l'appearV asv the description of the drawing proceedsffI'desire to have it understood, however,` that I do not intend to limit myself to the particular details shown and described, except as defined by the claims. y

AFig. 5 'is a section taken on the line 5--5 of Fig.2. r v v .Fig 6 isv afragmentary vertical sectional view through a portion of aheadlight showing a modification of myfinvention, vand L Fig-.LT is a-planview of the mounting block used inl conjunction with the form of invention shown inl'ig. 6.*k =f Referring in detail to the drawing, my inventiorr' is shown as being applied to a headlight havingjareflector I0, a :casing portion II and a lens I2-. Apairof .openings I3 is also provided in the casing-.Lhwhiche may be in the form of slots. A: tubular standard I4 is provided for the support of lthev lamp in the headlight, and said standard I4 isprovi'ded with a base flange I5, whichhas a pairof threaded openings I6 therein thatare `adapted to receive the screw-threaded headed fastening members I'I, which extend through the slots .I3 and which also extend through a slotHISiin the mounting block I 9.

e SaidmountinglblockIS is provided with openingsY 20 vfor fixing the same in position onY the casing II by means of rivets or similar fastening members, 4or the block may be soldered or brazed tothe casing- Hif f The'block I9`is made with its upper; facezparallel toi the'axis of the reflector I0 and with'jjthejlower face thereof conforming to theshape of the casing I I at the' point of securement thereto, vthe upper surface of the block' I9 flat and it will thus be evident that the standard I4 can be moved along the top of the block I9 either backward or forward in the direction of the slot I8 to the extent permitted by said slot I8, whereby the standard I4 can be moved bodily parallel to the axis of the reflector I so as to focus the headlight.

The standard I4 has the main portion thereof extenting in a substantially vertical direction and has a rearward bend at 2| providing an upper end portion 22 that is inclined at an oblique angle to the portion I4, and at an oblique angle to the axis of the reilector I0 so that the upper extremity 23 thereof faces the reflector I0, and the axis of the portion 22 would intersect the reilector I0 above its vertex. The axis of the inwardly and rearwardly inclined portion 22 of the standard I4 preferably makes an angle of approximately 15 degrees to the axis of the reflector I0.

The upper side of the tubular member 22 at its upper extremity 23, is provided with an ear or lip portion that is formed by spreading the end of the tube forming the standard, laterally, and shaping the saine so that it will be substantially flat and will extend at an oblique angle to the tubular portion 22 to provide a shield 24, which extends upwardly and inwardly at `an oblique angle from the point where it joins the member 22, thus extending not only at an oblique angle to the axis of the tubular portion 22, but also at an oblique angle to the axis of the reflector. 'Ihe shape of the member 24 is shown more clearly in Fig. 3, and has a relatively narrow portion 25 where it joins with the tubular portion 22, but is extended laterally so as to provide a relatively short shield in a vertical direction, but which is elongated considerably in a transverse direction.

It will be obvious that the shield 24 can be formed from the tubular member 22 by providing a longitudinal slit in the tubular member, and a pair of transverse slits therein, whereby the tubular member can be opened up and spread out into a flat form, but the shield portion will still remain integral with the tubular iportion 22. The shield 24 may be chromium plated if desired, to provide a reflecting surface thereon facing the lamp bulb 26 of the usual double filament type, through which the axis of said reflector passes between said filaments. i

The standard I4 is slotted in the tubular portion 22 thereof so as to provide a long longitudinal slot 21 therein having a lateral offset 28 therein between the ends thereof, said lateral oset 26 having an enlargement such as is commonly provided in a bayonet slot. Preferably a pair of slots 21 is provided at diametrically opposite points, and a substantially cylindrical insulating plug 29 tting within the cylindrical passage in the portion 22 of the standard I4 has a pair of projections 30 that are adapted to be received in the slot 21, the slot 21 thus limiting the inward movement of the insulating plug 29. The insulating plug 29 carries a pair of contact pins 3l and 32 in longitudinal passages provided therein, which are provided with springs 33 for forcing the same outwardly and which have the conductors 34 and 35 electrically connected therewith in any suitable manner, the conductors 34 and 35 being mounted in a cord or cable 36 that extends lengthwise through the tubular member I4 to an opening 31, through which said cord 36 passes into the space 38 between the reflector I0 and casing II and from that point out of the headlight in the usual manner to suitable switching means provided for manipulating the supply of current to the lamp 26 to burn the same brightly or dim the same.

The contact members 3I and 32 engage with the usual contacts 39 and 40 provided on the base portion 4I of the lamp 26, said base portion having the usual projections 42, which are adapted to engage in the lateral offsets 28 of the slots 21, thus holding the contacts 39 and 40 in engagement with the contacts 3l and 32, with the springs 33 under slight compression.

If the wiring for the headlight is to be concealed, but is to come out through the casing instead of passing between the casing and the rellector, the arrangement shown in Fig. 6 and the adjustable block shown in Fig. 7, are adapted to be used instead of the form of the invention shown in Figs. 1 to 5 inclusive. The standard I4 shown in Fig. 6, is made in the same manner as previously described, except that the tubular portion has no opening 31 therein, the conductor cord 36 extending downwardly through the opening in the bottom of the member I4 and through the opening I8 in the casing I I.

The block I9' is made in a similar manner to the block I9, being secured to the casing II in the same manner as previously described, but instead of being provided with a slot, is provided with a relatively large central opening 44, which is elongated in the direction of the length of the block I9, and has narrow extensions 45, which are slots serving the purpose of the slot I8 shown in Fig. 4. The fastening elements I1 extend through the portions 45 of the opening and the relatively large portion 44 of the opening is provided to accommodate the conductor 36 so that the standard I4 can be adjusted on the block I9 in the same manner as can the standard I4 on the block I9. The block I9 is made with a plane or ilat top face so as to permit sliding of the ange I thereon, and the lower face of the block I9 is shaped to conform to the shape of the casing II for the purposes previously described. The opening I8 is preferably made to conform in shape substantially to that of the opening in the block I9.

What I claim is:

1. In a headlight, a concave reflector, a standard having one end thereof located adjacent the axis of said reflector, a lamp socket on said end of said standard having a lamp receiving opening facing the inner portion of said reflector, the axis of said socket extending at an oblique angle to the axis of said reflector approximating degrees, a base for said standard and means for slidably mounting said base for adjustment parallel to the axis of said reflector to move said socket along said axis to focus said headlight, said mounting means being so constructed as to maintain the same angular relation of the axis of said socket to the axis of said reflector for any adjusted position thereof along said axis.
